技术问答

一、产品介绍：

光电耦合器又统称光耦继电器英文称MOS Relay又称PHOTO MOS RELAY 或PHOTO RELAY，归类为半导体固态继电器其中的一种，结合半导体与光电科技发展而成的光电类零件。光耦继电器属于没有可动触点的半导体继电器，因此在寿命和可靠性、动作速度、尺寸等方面优于传统的电磁继电器。但它们也有别于其他利用光电耦合器、光电晶体管等的开关解决方案。光耦继电器具有MOSFET用于输出，因此它们是最适合小模拟信号开关的器件，同时输入与输出间的隔离电压可达数千伏特以上。

二、动作工作原理

应LED加电流(电压)，使LED芯片发光，PVG芯片受光后产生电压及电流，利用此电压及电流控制开关(MOSFET)。

三、光耦继电器的优势

1、体积面积小型化（PIN距2.54mm）、重量轻、便于安装和使用更节省空间。

2、无机械触点解决接触磨损等寿命问题，可靠性高、寿命长。

3、低输入电流/低电压驱动（驱动电压0.9-1.5V/电流5-50MA）。

4、优良的开关特性：（高速、低噪音）。

5、支持热机切换。

6、防EMI，RFI干扰低失真、低噪声、高隔离、高绝缘电压：输入与输出间的隔离电压可达数千伏特以上，更加保证电路的安全和稳定。

四、光耦继电器的应用市场

1.医疗设备-Medical Equipment：如心电图仪、脑电图仪、X光设备及CT扫描仪，可以准确传输低频讯号。

2.汽车电池管理系统-BMS SOLUTION与电网储能应用-Power Storage System：如电池充电与放电应用、监控应用、绝缘检测和切断功能、平衡电路应用。

3.仪器仪表-Instrumentation：用于测量扫描功能，自动零点补偿以消除零点误差和各种条件下的高速测量序列接口，主要应用于半导体产品测试设备上采用。

4.通信领域：控制基本通信电路的交流或直流讯号，甚至高频率信号。

5.安防监控领域-Telecommunications（感测界面和输出到警报）：适合应用于系统传感器的感测界面和输出的警报联系动作，具有低控制电流、高可靠性和长工作时间的特性，非常适合需要长时间运行的安防应用。

6.电力电子领域：如智能电表-Smart Meters应用于讯号传输与自动撷取电表讯号；以及电源管理、办公自动化控制、电机控制等。

7.工业、自动控制化领域：如智能家居、自动化生产线、PLC可程控器（PLC digital output module types）以卓越的可靠性和兼容性作为取代传统的机械继电器的数字化应用普遍选择。
